5. Phapang pakeng tsa SMD LED Display le COB LED Display
5.1 Encapsulation Size le Density
SMD encapsulation e na le litekanyo tse kholoanyane tsa 'mele le bophahamo ba pixel, e loketseng mefuta ea kahare e nang le bophahamo ba pixel ka holimo ho 1mm le mefuta ea kantle e kaholimo ho 2mm. COB encapsulation e felisa khase ea lifaha tsa LED, e lumellang hore ho be le boholo bo nyane ba encapsulation le pixel density e phahameng, e loketseng lits'ebetso tse nyane tsa pixel pitch, joalo ka mefuta ea P0.625 le P0.78.
5.2 Ts'ebetso ea Pontšo
SMD encapsulation e sebelisa mehloli ea leseli, moo meaho ea pixel e ka bonoang haufi, empa ho tšoana ha mebala ho lokile. COB encapsulation e sebelisa mehloli ea leseli e holim'a metsi, e fana ka khanya e ts'oanang haholoanyane, pono e pharalletseng, le granularity e fokotsehileng, e etsa hore e tšoanelehe bakeng sa ho shebella haufi-ufi maemong a joalo ka litsi tsa litaelo le li-studio.
5.3 Tšireletso le Tšireletseho
SMD encapsulation e na le tšireletso e fokolang hanyenyane ha e bapisoa le COB empa e bonolo ho e boloka, kaha lifaha tsa LED ka bomong li ka nkeloa sebaka habonolo. COB encapsulation e fana ka lerōle le betere, mongobo le ho hanyetsa ho ts'oha, 'me li-skrini tsa COB tse ntlafalitsoeng li ka fihlela boima ba 4H holim'a metsi, ho sireletsa khahlanong le tšenyo ea tšusumetso.
5.4 Litšenyehelo le Mathata a Tlhahiso
Theknoloji ea SMD e hōlile empa e kenyelletsa mokhoa o rarahaneng oa tlhahiso le litšenyehelo tse phahameng. COB e nolofatsa ts'ebetso ea tlhahiso mme e fokotsa litšenyehelo, empa e hloka matsete a bohlokoa a lisebelisoa tsa pele.
6. Bokamoso ba SMD LED Display Screens
Bokamoso ba lipontšo tsa LED tsa SMD bo tla shebana le ntlafatso e tsoelang pele ea theknoloji ho ntlafatsa ts'ebetso ea ponts'o, ho kenyelletsa le boholo bo nyane ba encapsulation, khanya e phahameng, tlhahiso ea mebala e mengata, le li-angles tse pharalletseng tsa ho shebella. Ha tlhoko ea 'maraka e ntse e hola, li-skrini tsa SMD tsa LED li ke ke tsa boloka boteng bo matla makaleng a setso joalo ka papatso ea khoebo le mabala a lipapali empa hape li tla hlahloba lits'ebetso tse hlahang joalo ka filimi ea sebele le tlhahiso ea xR. Tšebelisano 'moho le ketane ea indasteri e tla tsamaisa katleho ka kakaretso, e ruisa likhoebo tse holimo le tse tlase. Ho feta moo, ts'ireletso ea tikoloho le mekhoa e bohlale e tla ama nts'etsopele ea nako e tlang, e sutumelletsa lipontšo tsa SMD LED ho lebisa ho tharollo e tala, e sebetsang hantle le e bohlale haholoanyane.
7. Qetello
Ka bokhutšoanyane, li-skrini tsa SMD LED ke khetho e ratoang bakeng sa mofuta ofe kapa ofe oa sehlahisoa kapa kopo. Li bonolo ho li theha, ho li hlokomela, le ho li sebetsa, 'me li nkuoa li le bonolo ho feta likhetho tsa setso. Haeba u na le lipotso tse ling, ikutloe u lokolohile ho li arabaikopanye le rona hona joalebakeng sa thuso.
